Springs are used in hydraulic systems, shift levers, and tracks (crawlers)!
We would like to introduce our solution for construction machinery from Higashi Hane. Powerful springs that provide great force (load) in a small space are used in hydraulics. Since painting on the springs can peel off and cause clogging, we offer powerful springs without any coating. If you are using round wire coil springs in a double configuration (where the spring is placed inside the inner diameter of the spring), please let us know. There may be potential for cost reduction by using powerful springs in a single (individual) configuration. Additionally, tension springs are used for the shift lever, and large springs are used for the tension of the tracks (crawler). Please feel free to contact us when you need assistance. *For more details, please refer to the PDF document or feel free to reach out to us.

Company information
The powerful springs that were first standardized in Japan using non-circular cross-section materials have become the standard in Japan. Based on customer requests, we have standardized high deflection powerful springs and powerful spring α. The resin guide has been developed and standardized to maintain the original lifespan of the springs. Additionally, they are adopted in manufacturing machines and presses used worldwide, based on the international standard ISO 10243, such as ISO STANDARD. We offer sizes that match manufacturing machines used in various industries around the world, ensuring high strength and durability.
